What CalWin does
CalWin AS is a Norwegian software company, headquartered in Ålesund and founded in 1985, that develops and sells an ERP system purpose-built for window and door manufacturers. Its platform covers the full operational workflow: quoting, sales and CRM, production planning, capacity management, machine integration (Homag, SCM, and others via XML/Oracle formats), warehouse and logistics, multi-location coordination, invoicing, EDI, and accounting system integration. The product is modular, with specialized capabilities for non-standard geometries such as round and arched windows, and runs on an Oracle database with an open architecture exposed via a SOAP-based CalWin Server web service. The current deployment is the Windows-based CalWin 7; a cloud-native, browser-based successor called CalWin 8 is launching via version 8.1 in September 2026, with Nordic data center hosting, automatic updates, and two-factor authentication.
Revenue is generated primarily through software licenses and subscriptions (transitioning to a fixed monthly model under CalWin 8), supplemented by consulting, implementation, and training services delivered by an in-house team of industry-specialist consultants. The company additionally holds an equity stake in Octaos AS, whose Octaos Webshop it bundles as a distribution channel. CalWin sells direct via a small field-sales motion (led by Sales Manager Johan Gardien) and through wholly-owned subsidiaries in the UK (CalWin UK, formerly Logical Bridge Ltd, acquired May 2024) and Lithuania (UAB CalWin), with on-the-ground consultants in Sweden and Norway.
The company serves over 50 enterprise customers across Norway, Sweden, the United Kingdom, and other markets, targeting a single vertical: window and door manufacturers ranging from small single-site factories to multinationals with multiple production, warehouse, and sales locations. The platform's specialization, twenty-five-plus years of accumulated domain expertise, long-tenured consulting staff, and deep integrations with machine vendors and EDI partners form the basis of its competitive positioning.

CalWin competitors and assessment
Company assessmentBroad incumbents
- Epicor Software: Epicor is a long-established ERP vendor focused on make-to-order and discrete manufacturing SMBs. It competes for the same kind of mid-market window/door manufacturer CalWin targets, but with a broad horizontal offering rather than vertical specialization.
- Sage Group (Sage X3 / Sage 100): Sage provides mid-market ERP including Sage X3 for process and discrete manufacturing, and has meaningful presence in UK and European SMB manufacturing — overlapping with CalWin's UK/Nordic footprint and mid-market window/door customers.
- Microsoft Dynamics 365 Business Central: Microsoft's mid-market cloud ERP is frequently the alternative considered by SMB manufacturers, including in Norway, Sweden and the UK. It competes on integrations, partner ecosystem, and cloud readiness rather than vertical depth.
- SAP Business One: SAP Business One targets the small-to-mid manufacturing segment globally with a strong partner channel. Larger window/door manufacturers in CalWin's customer range commonly evaluate SAP B1 as an alternative, particularly during digital transformation initiatives.
- Infor (CloudSuite Industrial / LN): Infor provides industry-specific ERP suites, including manufacturing (LN/CloudSuite Industrial) with deep process manufacturing capabilities. It serves as a step-up alternative for mid-market manufacturers outgrowing CalWin-sized vendors.
- IFS: IFS provides industry-focused ERP/EAM (including for industrial manufacturing and construction-adjacent sectors) with strong European presence. Larger or more digitized window/door manufacturers considering CalWin alternatives may evaluate IFS for enterprise-grade features.
Direct peers
- JobBOSS by ECI Software: JobBOSS is an ERP/MRP system aimed squarely at small and mid-sized job shops and custom manufacturers, including those with make-to-order workflows. It is one of the most direct competitors for the small-to-mid window/door manufacturer segment CalWin serves.
Emerging players
- Odoo: Odoo is an open-source / SaaS ERP with a Manufacturing module (MRP, PLM, maintenance) frequently adopted by small manufacturers. It competes on price and modularity and represents the modern-cloud alternative pressure on legacy on-prem ERPs like CalWin 7.
- Acumatica: Acumatica is a cloud-native mid-market ERP with a Manufacturing Edition that competes directly for SMB manufacturers, including those considering moves away from on-prem solutions. It represents cloud-first competitive pressure as CalWin migrates CalWin 7 customers to CalWin 8.
Regional players
- Visma: Visma is a leading Nordic-headquartered business software group providing ERP, payroll, and accounting solutions widely adopted in Norway and Sweden. It competes for back-office and operational software budgets at the same Nordic SMB manufacturers CalWin targets.
